FE Robust Tetrahedral Mesh

Create an FE Mesh of solid tetrahedral elements from a domain defined by a closed surface mesh that is known to have defects. This function will remesh the input domain to generate FEA quality elements in the volume. Note that this function is extremely robust and can handle severe defects. Although, the trade-off for this robustness is speed as the algorithm will be noticeably slower than other alternatives. This function is only recommended if the input domain is known to have severe defects.

Inputs

Name	Type	Description
Domain	Mesh	The input domain defined by a watertight surface mesh. The input surface mesh will be remeshed to obtain FEA quality elements.
Edge length	Scalar	The target edge length of the elements. Note that the input can be a scalar field to achieve a spatially varying mesh size.
Geometric order	Geometric Order Enum	The geometric order of the output mesh. The linear option may be suitable for a fast analysis, but quadratic elements are recommend when accuracy is more important. For quadratic elements, the mid-side nodes are inserted along the straight edges of the elements. That is, the quadratic elements are not curved.
